Have you tried clones?
Maybe if you build the object from parts made from clones, then you could make a change to one and the rest of the "parts" would update?
So if the cube side where clones, once you made a change to the thickness of a side, the rest would be the same.
You could even make a component of the clone assembly..

I'm in the same boat Imagix.
I have the Dosch 2009 cars which I optimised years ago and still use in my renders, but I bought the 2018 cars which come without the maxwell materials.
So I've just started importing them (I prefer the low poly versions as I think they are good enough for my purposes) into Z using the LWO format (seems to import the materials and textures better).
There are approximately 26 materials in each car model, so the first thing I do is to "save a copy as" in Z to a new designated folder so I have the materials with texture maps together (about 6 image maps per car ie. number plate, logo etc.). The other materials without texture maps can be copied from the older cars for speed, renamed (altered if required) and re-assigned in Z.
Then create mxs in Z, open and edit if required in Maxwell Studio and Bob's your uncle.
The whole process takes about an hour or so, but if you squeeze one car in every fews days between jobs, you'll have a nice collection ( there are 15 cars in the 2018 collection).
Hope this helps,

I think that is a great bargain Phil!
I already have two licenses for just me so I won't be buying. I would suggest to anyone who has a single license to snap this offer up.
And anyone who's trying out Fz to get it!

It really depends on the type of object which has a missing face/s and whether the opening is planer or not.
If object doctor is unable to fix the missing face then you'll have to replace it yourself and stitch it to the rest of the object. The first thing I would try is to use "select sequence" in tool options, move the cursor over the edge of the missing face and if it selects the correct edges around the hole, copy and paste. If the edge you copied pastes in with a surface, then the surface is planer and can be stitched to the rest there and then. If the edge pastes in without a surface, then it's non-planer in which case use the triangulate tool on it and then stitch.
If you are unable to use the select sequence (the sequence goes beyond the opening for example) just trace the opening in a 3d view with the vector line (as a 2d surface) snapping to the points. If the closed vector line has no surface then do as above and triangulate it and stitch.
You can draw in triangles as well with the vector tool and stitch them together.
If you post a snapshot of the object with it's missing face, it'd be easier to choose the right method...

Surely this is not a question of your opinion of 3d software? Vray is a new implementation in FormZ and obviously needs tweaking, give it time.
My advice.. get another job, nobody should be forced to do anything...

Hi Spanner,
It displays fine on my machines, have you contacted Support directly?
Just thinking out loud, maybe try playing with the Fz OpenGL preferences? Try toggling the Multi Threading and Advanced OpenGL.
Don't know if that would help though...
